DETAILED DESCRIPTION OF INVENTION

Referring to FIG. 2, an embodiment of a display support primarily includes a sliding module S, a base module 30, and a constant spring 40. The sliding module S comprises a plastic first integral-formed frame 10 and a plastic second integral-formed frame 20 movably received therein. As shown in FIG. 2, the base module 30 comprises a receiving portion 31 with the sliding module S joined therein. The constant spring 40 connects the first and second integral-formed frames 10 and 20 of the sliding module S.

Referring to FIGS. 3A and 3B, the first integral-formed frame 10 comprises at least a hook 11, and the second integral-formed frame 20 comprises at least a slot 21 and a stopper 211 disposed therein. During assembly, the second integral-formed frame 20 is inserted into the first integral-formed frame 10, and the hook 11 is movably received in the slot 21. When the second integral-formed frame 20 slides with respect to the first integral-formed frame 10 to a limit position, as shown FIG. 3B, the hook 11 slides along the slot 21 and abuts the stopper 211, thereby presenting separation of the second integral-formed frame 20 from the first integral-formed frame 10.

Before using the support, as shown in FIGS. 4A and 4B, the second integral-formed frame 20 is retracted into the first integral-formed frame 10, and the sliding module S is in a retracted state for easy storage and package. In FIG. 4B, a nub 13 (first joining portion) projecting from an inner surface of the first integral-formed frame 10 is joined in a hole 221 (second joining portion) of the second integral-formed frame 20, thus preventing relative sliding between the first and second integral-formed frames 10 and 20. Referring to FIGS. 3A and 5, the hole 221 is formed on a flexible structure 22 of the second integral-formed frame 20, such as longitudinal cantilever extended along Z axis. When the second integral-formed frame 20 is retracted into the first integral-formed frame 10, the flexible structure 22 is pressed by the nub 13 and slightly deformed.

Referring to FIGS. 6 and 7, when using the support, the sliding module S in the retracted state is inserted into the receiving portion 31 of the base module 30. Here, a latch 12 of the first integral-formed frame 10 is engaged with an opening 331 of the receiving portion 31, as shown in FIG. 7, thus fixing the sliding module S to the base module 30. Simultaneously, as shown in FIGS. 8A and 8B, a slope 321 of a protrusion 32 of the receiving portion 31 pushes against the flexible structure 22 of the second integral-formed frame 20, such that the nub 13 separates from the hole 221. Hence, the second integral-formed frame 20 is released from the retracted state and movable with respect to the first integral-formed frame 10 along Z axis for height adjustment of the support.

In this embodiment, the sliding module S can be shortened and held in the retracted state when the support is not in use, thus saving volume of product and cost of package. When using the support, the sliding module S is simply inserted into the receiving portion 31 of the base module 30, such that the second integral-formed frame 20 is released from the retracted state for extension of the support.

Referring to FIG. 9, another embodiment of a display support primarily comprises a sliding module S, a base module 70, and a constant spring 80. The sliding module S comprises a first integral-formed frame 50 and a second integral-formed frame 60 movably received therein. The constant spring 80 connects the first and second integral-formed frames 50 and 60. As shown in FIG. 9, the base module 70 comprises a pedestal 71, a slider 72, a releasing member 73, and a spring 74. The pedestal 71 comprises a receiving portion 711, and the slider 72 comprises a latch 721, two protrusions 722 and a contact portion 723.

In this embodiment, the slider 72 is movably received in the receiving portion 711. The releasing member 73 is disposed through a through hole 712 of the receiving portion 711 and connected to the contact portion 723. The spring 74 is disposed around the releasing member 73 and abuts the contact portion 723 and an inner wall of the receiving portion 711. When the support is not in use, the sliding module is in a retracted state with the second integral-formed frame 60 retracted in the first integral-formed frame 50. When using the support, the sliding module S in the retracted state is inserted into the receiving portion 711 of the base module 71. Thus, the latch 721 of the slider 72 is engaged with an opening 51 of the first integral-formed frame 50, as shown in FIGS. 9 and 10, such that the sliding module S is fixed to the base module 71.

During insertion of the sliding module S into the receiving portion 31, as shown in FIGS. 11A and 11B, a slope 7221 of the protrusion 722 pushes against a flexible structure 61 of the second integral-formed frame 60, such that a nub 52 (first joining portion) of the first integral-formed frame 50 disengages from corresponding hole 611 (second joining portion) of the second integral-formed frame 60. Hence, the second integral-formed frame 60 is released from the retracted state and movable with respect to the first integral-formed frame 50 along Z axis for extension of the support. Specifically, when the user pulls the releasing member 73, as the arrow indicates in FIG. 10, the latch 721 of the slider 72 is moved with the releasing member 73 and disengaged from the opening 51 of the first integral-formed frame 50, such that the sliding module S is detached from the base module 70.

Referring to FIG. 12A, another embodiment of a sliding module S′ comprises a first integral-formed frame 91, a second integral-formed frame 92, and a cover 93 fixed to an end of the first integral-formed frame 91. The second integral-formed frame 92 is movably received in the first integral-formed frame 91 and disposed through the cover 93. As shown in FIGS. 12B and 12C, the first integral-formed frame 91 has a longitudinal first connection portion 912, and correspondingly, the second integral-formed frame 92 has a curved second connection portion 923. A resilient member R, such as a constant spring shown in FIG. 14C, is hooked on the first connection portion 912 and naturally abuts the second connection portion 923 by spring force thereof, facilitating stable sliding and connection between the first and second integral-formed frames 91 and 92.

Referring to FIG. 13A, the sliding module S′ is joined in a base module 94 and connected to a hinge mechanism H for supporting a display (not shown), wherein the display can be hung on the hinge mechanism H and capable of height adjustment. Before joining the sliding module S′ to the base module 94, the sliding module S′ is in a retracted state with the second integral-formed frame 92 hidden in the first integral-formed frame 91, as shown in FIG. 12A, wherein a recess 911 (first joining portion) of the first integral-formed frame 91 is engaged with a clasp 9211 (second joining portion) of the second integral-formed frame 92.

Referring to FIG. 13B, when the sliding module S in the retracted state is inserted into the base module 94, the first integral-formed frame 91 is fixed to the base module 94. Simultaneously, the clasp 9211 of the second integral-formed frame 92 is pressed and deformed by a slope 941 of the base module 94, as the arrow shown in FIG. 13B. Hence, the clasp 9211 is disengaged from the recess 911, such that the second integral-formed frame 92 is released from the retracted state and movable with respect to the first integral-formed frame 91 for height adjustment of the support.

Referring to FIGS. 12 and 14A˜14C, when the second integral-formed frame 92 slides to a limit position with respect to the first integral-formed frame 91, a rib 922 around the second integral-formed frame 92 abuts the cover 93, as shown in FIGS. 14B and 14C, thus preventing separation of the second integral-formed frame 92 from the first integral-formed frame 91.

Referring to FIG. 14C, as the resilient member R is hooked on the first connection portion 912 and naturally abuts the second connection portion 923 by spring force thereof, an upward force is exerted on the second integral-formed frame 92 for easy extension of the support. As shown in FIGS. 14C and 14D, the resilient member R is positioned between two ridges 9122 on a surface 9121 of the first connection portion 912, preventing deviation of the resilient member R along X axis and facilitating stability of the sliding mechanism.

In this embodiment, the first and second connection portions 912 and 923 are integrally formed with the first and second integral-formed frames 91 and 92 respectively, comprising a screw-less sliding mechanism. Furthermore, as the resilient member R connects the first and second connection portions 912 and 923 merely by spring force thereof, no screw or fastener is required for assembly, thus reducing production cost thereof.

The invention provides a display support comprising a sliding module having two integral-formed frames, capable of a screw-less structure and less number of parts than conventional support mechanism. In particular, when the support is not in use, the sliding module can be retracted for easy storage and package thereof.
